Ok so I'm down to the last thing on the car. I'm drilling out the control arms and installing grease fittings. I mentioned it before and somebody remarked on the grease. I have never heard of such a problem but it does seem possible so I looked online and didn't see anything. Have you ever heard of a problem where axle grease had a reaction with aluminum? Do you know what grease is in the control arms?

 

Drilling out the control arms? You just want to change out the bushings on the upper links or what? Those are pressed in, grease shouldn't have an effect on aluminum. Un-less its a solvent based oil/grease, which i don't know of any that exist.

 

No I just want to put grease fittings in them. I'm one of those reatards that greases his front end. Why don't these cars have fittings damit. I am hoping that .50 cents of grease will help them last longer.

 

Wouldn't drilling them out increase the chance that they'll fail in the long run anyway?

 

They have a steel cap on top and the reason these things fail is because the grease liquifies and seeps out. Here in Florida I grease my Mack once a week as in New york I did it once a month. It's this friggin heat I tell ya. It liquifies this ****. I'm sure the car will only need a small squirt once a year but it's better than nothing.
Drilling and installing a fitting in the top wouldn't make it fail metal to metal will make it fail. I saw a guy do it on line some where.

 

I think its a terrible idea, grease fittings are for trucks. None of our links have grease in them BTW, they are all solid bushings.

 

Just chamfer the holes.. aluminum fails at a sharp edge first.

Dont worry about the grease. Anything you or I would buy is compatible.

Pack the grease gun with hi-temp wheel bearing grease.

 

All right we’re in two different places I am talking about the ball joints of the control arms. I obviously have not had one fail. Where do they normally fail? The way you’re both talking sounds like the ball is not the place they fail, the bushing is. How often do they fail anyway? I can’t just drill out the bushings there would be no place for the grease to rest they would need groves cut around the bushing it would be a waste of time and wouldn’t work they would just end up leaking grease onto the rotor. I saw a video of some guy putting fittings into the top of the ball joint casing and assumed that is where they failed. Keep in mind guys I have never owned a car myself. All vehicle purchases have been 3500 Chevy’s to Mack’s Pete’s Komatsu Cat Grease has been imbedded into my mind it is an expensive mistake to make on that crap.(besides I have buckets of the ****) So that’s the story I’m just trying to prevent wear and tear as much as possible.

 

Exactly, the ball joints almost never fail before the bushings do. Changing the bushings is next to impossible without a 2 ton press and even then it sucks. Replacement of the links (that come with ball joints) is the way to go. You can buy an entire repair kit that comes with every link on the front of the car for about $550 from www.ecstuning.com Thats the ONLY way to roll with our cars.

 

Update, i did a little search for you and for some stupid damn reason the 3.0L A6 doesn't have a kit available... Why i have no idea, the 2.7 and 2.8L kit look like this.http://www.ecstuning.com/Audi-C5_A6-...on/OEM/ES3005/
I didn't think the 3.0L control arms would be any different but who knows, i might give them a call to get the skinny.
